Abstract
A memory control device and method receives a request to transfer a series of first-unit K byte (for example, 512) data in an address space, divides the first-unit K into second-unit L (for example, 64), assigns priority levels to the second-unit L, issues plural times a data transfer instruction to transfer the L-byte data to a memory device comprising a plurality of memories operable in a consecutive access mode, and thus accesses memories in response to the request to transfer the K-byte data. The L-byte data are sequentially allocated in third units S (for example, 64) specified by the data transfer instruction to the memories. The third unit is equal to L or is obtained by dividing L, and is a multiple of an activation unit of the memories. The S-byte data are accessed in the allocated memories in the consecutive access mode.
